Wiki PageID
by Gintautas Sulskus 05 Oct '18

05 Oct '18

Hi, I have a couple of questions regarding the Wiki Page ID. Does it always stay unique for the page, where the page itself is just a placeholder for any kind of information that might change over time? Consider the following cases: 1. The first time someone creates page "Moon" it is assigned ID=1. If at some point the page is renamed to "The_Moon", the ID=1 remains intact. Is this correct? 2. What if we have page "Moon" with ID=1. Someone creates a second-page "The_Moon" with ID=2. Is it possible that page "Moon" is transformed into a redirect? Then, "Moon" would be redirecting to page "The_Moon"? 3. Is it possible for page "Moon" to become a category "Category:Moon" with the same ID=1? Thanks, Gintas

Wikidata HDT dump
by Laura Morales 02 Oct '18

02 Oct '18

Hello everyone, I'd like to ask if Wikidata could please offer a HDT [1] dump along with the already available Turtle dump [2]. HDT is a binary format to store RDF data, which is pretty useful because it can be queried from command line, it can be used as a Jena/Fuseki source, and it also uses orders-of-magnitude less space to store the same data. The problem is that it's very impractical to generate a HDT, because the current implementation requires a lot of RAM processing to convert a file. For Wikidata it will probably require a machine with 100-200GB of RAM. This is unfeasible for me because I don't have such a machine, but if you guys have one to share, I can help setup the rdf2hdt software required to convert Wikidata Turtle to HDT. Thank you.

Wikiata and the LOD cloud
by Ettore RIZZA 08 May '18

08 May '18

Hi all, The new version of the "Linked Open data Cloud" graph <http://lod-cloud.net/> is out ... and still no Wikidata in it. According to this Twitter discussion <https://twitter.com/AmrapaliZ/status/990927835400474626>, this would be due to a lack of metadata on Wikidata. No way to fix that easily? The LOD cloud is cited in many scientific papers, it is not a simple gadget. Cheers, Ettore Rizza

Use Repology to update software package data
by David Kleuker 02 May '18

02 May '18

Hello, i want to inform you that Repology has your "repository" of software versions included and can list problems or outdated versions that way. https://repology.org/repository/wikidata https://repology.org/repository/wikidata/problems https://repology.org/metapackages/?inrepo=wikidata&outdated=1&families_newe… https://repology.org/metapackages/?inrepo=wikidata&outdated=1&families_newe… You might want to give that information to the maintainers of this data set. I havn't found a portal or place for related informations. It is probably possible to automatize this somehow. Just ask a human for source link that package actually has that version now or scrape the projects download page for that version string and use that. Are you interested to import data from there? Like when a version is available in more than 10 repositorys trust and import it. You can ask for such a feature (with compatible license) here: https://github.com/repology/repology I hope that helps you to make Wikidata better. It's a great project! kind regards davidak

Re: [Wikidata] How to find the Dbpedia data for a Wikidata
by Christopher Johnson 30 Apr '18

Hi Scott, One way to do that would be to get the language code label list from WDQS with this: http://tinyurl.com/y9p7q9l2 SELECT ?label WHERE {?s wdt:P424 ?code; rdfs:label ?label filter (lang(?label) = "en").} and then stream the list to LDF client [1] requests https://tinyurl.com/ycc3dyce ldf-client https://query.wikidata.org/bigdata/ldf http://fragments.dbpedia.org/2015-10/en "SELECT * WHERE {?s rdfs:label "+ language + "@en . ?s owl:sameAs ?link }" The results would be in JSON from the client. It should give a relatively complete list of WIkidata language code entity corresponding resources in DBpedia Also, an simple way to get a dbpedia resource with TPF is with the entity label which is one of the properties that is the same for both datasets. So, SELECT * WHERE { ?s rdfs:label "German"@en . } will return the matching dbpedia and wikidata resources for that label. This could also perhaps be done with a federated query in WDQS.(untested).

Call for Papers: Industry Track2. Call for Papers: Poster and Demos3. Call for Papers: Outrageous Ideas Track1. Call for Papers: Industry Track==========================================The industry track seeks to present the state of adoption of semantic technologies in industrial settings. Semantics is used in applications in many industries, including media, financials, telecommunications, healthcare, life sciences, government, intelligence, smart cities, and cultural heritage. It enables applications capabilities as varied as business intelligence, analytics, search, content management, knowledge management, recommendation systems, information extraction and data integration.We encourage results and ideas from companies large and small. We welcome contributions about success stories as well as experience reports and discussions of obstacles that stand in the way of large-scale adoption of semantic technologies.Detailed info: http://iswc2018.semanticweb.org/call-for-industry-track-submissions/ <http://iswc2018.semanticweb.org/call-for-industry-track-submissions/> == Important Dates == Full papers due: June 1, 2018Notifications: June 22, 2018Camera-ready due: July 20, 2018== Program Chairs ==* Vanessa Lopez, IBM Research, Ireland* Kavitha Srinivas, Rivet Labs, USA2. Call for Papers: Poster and Demos==========================================The ISWC 2018 Posters and Demonstrations complement the paper tracks of the conference and offer an opportunity for presenting late-breaking research results, on-going research projects, and speculative or innovative work in progress. The informal setting of the Posters and Demonstrations encourages presenters and participants to engage in discussions about the work. Such discussions can be invaluable inputs for the future work of the presenters, while offering participants an effective way to broaden their knowledge of the emerging research trends and to network with other researchers.We invite submissions relevant to the area of the Semantic Web and which address, but are not limited to, the topics of the Research Track; the In-Use Track; and the Resource Track. Technical posters, reports on Semantic Web software systems (free or commercial), descriptions of completed work, and work in progress are all welcome. Demonstrations are intended to showcase innovative Semantic Web related implementations and technologies, both in academia and in industry.Detailed info: http://iswc2018.semanticweb.org/call-for-posters-demos/ <http://iswc2018.semanticweb.org/call-for-posters-demos/> == Important Dates == Full papers due: June 1, 2018Notifications: June 22, 2018Camera-ready due: July 24, 2018== Program Chairs ==* Medha Atre, Indian Institute of Technology Kanpur, India* Marieke van Erp, KNAW Humanities Cluster, the Netherlands3. Call for Papers: Outrageous Ideas Track==========================================The Outrageous Ideas track is back to ISWC! Similarly, as in 2011, this track is sponsored by the prestigious CCC Blue Sky ideas and solicits visionary ideas, long term challenges, and opportunities in the semantic web research that are outside of the current topics in the field and are not mature or specific enough to be accepted in the regular research track. The contributions should find the right arguments to convince that the proposed topic is promising and should relate the talk as much as possible to the existing literature from relevant fields, possibly also fields outside the Semantic Web Community.Detailed info: http://iswc2018.semanticweb.org/call-for-outrageous-ideas-track-papers/ <http://iswc2018.semanticweb.org/call-for-outrageous-ideas-track-papers/> == Important Dates == Full papers due: June 1, 2018Notifications: June 22, 2018Camera-ready due: July 20, 2018== Program Chair == * Carolina Fortuna, JSI, SloveniaAll deadlines are midnight Hawaii time.The ISWC Organising Committee (http://iswc2018.semanticweb.org/organization/ <http://iswc2018.semanticweb.org/organization/>)*

Six months left before Wikidata's sixth birthday
by Léa Lacroix 30 Apr '18

30 Apr '18

Hello all, *(sorry for crost-list posting)* Every year since Wikidata went live, on October 29th, 2012, the Wikidata community celebrates its anniversary all around the world. Local groups organize meetups, workshops, share cake and greetings, to celebrate the work of the editors building up the knowledge base and its ecosystem of tools. Last year, for the 5th birthday, the WikidataCon <https://www.wikidata.org/wiki/Wikidata:WikidataCon_2017/Documentation>, first international conference dedicated to Wikidata was organized in Berlin. Waiting for its return in 2019, the local events continue! We encourage the community to meet up, the chapters and user groups to organize events in order to build a Wikidata group in their area. Even if you're just starting editing, or you've never been organizing an event before, you can be part of the Wikidata's sixth birthday! The events will take place around October 29th, 2018 (it doesn't have to be on this exact day). You can find a lot of information on this page: https://www.wikidata.org/wiki/Wikidata:Sixth_Birthday You will find the list of events that will take place around the world, ideas of formats, ways to get funded, and documentation about organizing events. We're excited to see many small or big Wikidata events happening everywhere! If you have any question or need help, feel free to contact me.
